and PIRQ tables were actually wrong, I cannot imagine they ever
worked properly.
- Use CONFIG_IRQ_TABLE_COUNT in all irq_tables.c files instead of
hard-coded numbers.
- Make all CONFIG_IRQ_TABLE_COUNT values in irq_tables.c match Options.lb.
- Make all CONFIG_IRQ_TABLE_COUNT values match the actual number of entries
in the irq_tables.c file.
- Set all CONFIG_IRQ_SLOT_COUNT values in src/.../Options.lb for those
boards where they were set to 0 (in order to be overridden in
the respective targets/.../Config.lb).
This is mainly done to aid Patrick's scripts for kconfig conversion.
- Fix a number of comments in irq_tables.c files.
- Drop CONFIG_IRQ_SLOT_COUNT usage from boards that don't have irq_tables.c:
- tyan/s1846
- asus/a8v-e_se
- asus/m2v-mx_se
